I am trying to get a wiring diagram on the Multifunction lever in the cab part no 0005474911. Its the lever with all the buttons on it( header front up/down, Auger in/out, Reel, auto steer etc.!! Does any one know how to pull it apart im trying to used the auto steer button to control my Trimble fx750 auto steer. My class service people tell me it cant be done but im sure it can. Any one got any info on this or done it before Thanks
